The frequency is the same. The camshafts rotate half the speed of the crank which is why I wanted verify. You need to check your oil. I would not run the car at all until this is fixed. Tow it if you aren't a DIYer.
    I managed to take the valve cover off and I was checking the cam bolts and everything seems fine but I found another thing. Could this be the noise that I am having?Click image for larger version

      Not sure if this is the noise, it could be, but your hub broke a tab. Stop driving the car, time for a full vanos job. you’re one of the lucky ones that it got caught in the disk itself and didn’t fall into your engine.

      Beisan now sells an upgraded hub, which is what you should replace your broken hub with, alongside all of the beisan seals, solenoid, upgraded pump disk, and cam bolts.

      while you’re in there, you’ll have a good chance to inspect everything else, adjust the valves, etc.

        I was in the same situation last year, broken tab on the hub. I only had a marble noise around the 2700 rpm (+/- 200) range.

        I went with the TT hub as it wasn't yet offered through Beison. Here's my cost break down, I did the labor myself by printing the Beison procedure.

          Jon, do not drive the car anymore. You need to get the full VANOS job done. Where are you located?
          Youtube DIYs and more

          All jobs done as diy - clutch, rod bearings, rear subframe rebush, vanos, headers, cooling, suspension, etc.

          PM for help in NorCal. Have a lot of specialty tools - vanos, pilot bearing puller, bushing press kit, valve adjustment, fcab, wheel bearing, engine support bar, etc.

            Of you're around Orlando I can help you out. Definitely don't drive the car unless it's an absolute emergency. It looks like the piece already fell into the oil pan to me.

                        THOSE cam bolts I would not reuse (a little joke from a different thread ).

                          Does anyone have a clip (even just the sound) of this "marble noise" around this rpm range? I'm suspicious of a a rattle I seem to hear at around 2,500rpm when cold. Thanks.
